I've got some clones rooting, so hopefully I'll be able to do a sort-of side by side. (top and bottom) Will have to remove some bulbs from bottom (late veg) space to make 'em even-stephen, but if Farmer Bob's advice is correct, I might not miss the missing lumens.

Kinda off-topic...but this is my latest veg closet. Half clothes, half growroom.

The drip trays are lined with aquarium gravel, so I don't need drainage rocks taking up room in the pots, and makes transplanting a breeze. Clone tray cover is a sheet of plexiglass. Holds 12 clones. The plastic tray and bulb bases (outdoor security lights) are both from WalMart, UV light is in the bottom section. The shade cloth keeps the light from glaring off my computer screen. (and no signs of the bulbs melting it at all) Has an unlighted upper level (not shown) for a tub of just-planted seeds. (versatility)

Anyway, I guess we'll see how it goes. :jointsmile:
Rusty Trichome Reviewed by Rusty Trichome on . UVb an experiment Quick background: I have been using UVb supplemental lighting for many years now and have always thought it added to the finished product in a couple of ways. I had never promoted it's use on these boards because I felt it was dangerous and had real potential to harm people. That changed a few months back on the other UVb thread, and I came out of the closet in strong support of it's use. Well some here who's opinion I respect (like Weezard) held the opposite view and those discussions led me Rating: 5
